CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part (and claims the benefit of priority under 35 USC 120) of U.S. application Ser. No. 16/677,639 filed Nov. 7, 2019 currently pending. The disclosure of the prior applications is considered part of (and is incorporated by reference in) the disclosure of this application.

BACKGROUND

This disclosure relates generally to building construction and in particular, to the method, computer program, or computer system for providing the quality control of the material for the building construction and determining conflicts within the building construction.

A typical building or structure is comprised of having different components like foundation, walls, joists, trusses, sheathings, and many other components. When these components are connect with each other in a proper form, the structure or building is constructed correctly. Each individual component is used to form a larger assembly or panel. If each component is not with the correct specification or dimensions then it leads to conflicts in the assembly process. This results in lost of time, wasted material, and an increase in cost. For example, when constructing roof trusses, conflicts between the members of the panel can occur in overlapping of the members, wrong placing of dimples locations, insufficient overlap length, and overlap width. Checking each individual member and panel is very time consuming and critical task for the engineer.

During the building construction, the connections and placing of each roof trusses is important for a hassle and conflict free construction. The roof trusses relative to the other roof trusses assists in creating a building that is properly constructed. The assembly of the roof is important to avoid any issues with the building down the road and to keep the occupants safe from the elements. Traditional method of reviewing the constructability checks for each individual roof truss member panel manually in the detailing software is time consuming and chances of error are more.

Therefore, it is beneficial to assist each of the roof truss to roof truss horizontal and vertical interfaces at the earliest stage to determine where issues exist and preemptively correcting these issues before construction begins.

DETAILED DESCRIPTION

The present invention generally relates to the process of analyzing a building to identify conflicts or design errors, and correcting the errors at the design stage so the construction can be completed with minimal or no issues. Through the location of the roof trusses and the interaction between the roof truss interfaces to determine if they have the correct properties and if they are outside of the tolerance values, correcting the errors with the roof trusses.

The present invention uses the unique feature of analyzing the roof trusses and the interaction between the roof trusses in the horizontal and vertical interfaces and determining if there are any inter-assembly conflicts. This includes the vertical interfaces between the trusses, the horizontal interfaces between the trusses, and the interface between the structural trusses and the non-structural truss system. In instances where conflicts are identified the roof truss member(s) and/or assemblies are added to a sick list, which identifies the type of conflict. The unique feature saves the time of review the building manually and eliminate the chance of error with the construction process.

In the typical construction process a model of the building (e.g. structure, home, office building, hospital, garage, barn, apartment building, etc.) is created. This model is comprised of all the members which form the frame of the building. The members form assemblies (e.g. wall panels, joists, trusses, etc.) which them form the walls, floors, and roof. The next step is to generate the manufacturing files for the roll forming machine to produce these members to the design specifications. However, the generation of these manufacturing files is not advised or able to be completed until a verification of possible conflicts of the systems is completed.

Otherwise the potential for cold formed steel studs to be manufactured without the proper measurements, cutouts or designs elements. This will require the remanufacturing of the members, or manual modification of the parts need to be completed on the job site. Both of these take time and additional resources to complete. The reviewing of the model from constructability aspect and identify the possible conflicts is a time consuming task before the roof truss members are manufactured. If the user is able to quickly identify the conflicts in the model, the entire process of constructing the building can be shortened.

The reviewing of the 3D model from constructability aspect and identify the possible conflicts in the walls is one of the major time consuming task. If the user is able to quickly check and identify the possible conflicts, they can increase the speed of manufacturing, and having a program that highlights these conflicts only further increases the speed at which the project can be completed.

The present invention provides for an advantage of allowing the review of the drawings or models by providing a unique process of identifying internal and external conflicts with the roof truss members. The individual members of the roof truss which are conflicting are identified and marked for the reviewer to easily identify and correct the conflicts. The conflicts can be identified during the process of building detailing by using the present inventions conflict check method and system.

The term “conflict” is used for any incidence which results in the member or the interaction between members to be outside of a predetermined tolerance of acceptable values. This can be based on state, federal or local building codes, manufacturing machine limitations, or inconsistencies or inaccuracies with the model or drawings. For example, if a member is not at the required position, not within the required specifications, not adhering to predetermined codes, or the like a conflict may be present. Required position means the Global position of the member in reference to the modeling software x, y, and z, axes. In another embodiment, the properties of the member may be impossible to manufacture based on the cold formed steel construction tolling operation limitations

It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firejoists).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

Conflict Identification program 108 has the unique feature of constructability conflict check in which the roof truss system and assemblies are analyzed to determine if a roof truss has a conflict with another roof truss which interfaces with one another. The roof trusses which are conflicting with each other are added to a sick list which identifies all of the conflicting roof trusses. The conflict can be between any material, component, member or the roof trusses which interface with another roof truss which either interfere with one another or are not within the proper code requirements. The sick list shows the condition under which the member is conflicting in constructability conflict check, so personnel can easily make the necessary modifications to correct the conflicts and produce a model of the building without any conflicts.

Moreover, it is noted that some of the modules 42 can be implemented within the infrastructure shown in FIGS. 1-3.

FIG. 4 depicts flowchart 400 depicting a method according to the present invention. The method(s) and associated process(es) are now discussed, over the course of the following paragraphs, in accordance with one embodiment of the present invention.

In step 402, the conflict identification program 108 analyzes the model to identify the roof truss members. Based on the received model or image type, the conflict identification program 108 extracts the roof truss members from the other members and systems. In some embodiments where the model has all the members individually generated, the conflict program 108 is able to easily extract the roof truss members. Either from identifying the members first or identifying the roof truss assembly and then identifying the members within the roof truss. In instances where the model does not have each individual member created, the conflict identification program 108 analyzes the model or images to first determine which surfaces are roofs versus floors or walls. This analysis is based on the data extracted from the model that identifies the measurements of the roof based on the measurements of the building.

The conflict identification program 108 then identifies the roofs and generates a roof truss assembly comprised of members to provide for the required frame to create the model.

In step 404, the conflict identification program 108 identifies the roof truss members and analyzes the internal properties of the roof truss members. Once the conflict identification program 108 has identified the roof trusses, the conflict identification program 108 is able to identify the roof truss member individually so that the conflict identification program 108 is able to extract the necessary information related to each roof truss member. In some embodiments, the conflict identification program 108 identifies the position of the roof truss members relative to each other. For example, to make sure all horizontal members are substantially parallel and that the horizontal members are substantially perpendicular to the vertical members. For roof trusses the roof truss members are substantially parallel or perpendicular unlike with roof trusses and roof trusses.

The conflict identification program 108 determines the actual values for the roof truss member properties. These properties are related to all features of the roof truss member; length, height, width, thickness of material, orientation, position, cutouts, apertures, lips, flanges, Swedge, and the like. For example, the roof truss members position relative to the x, y, and z axes. In some embodiments, the limitation of the shipping vehicles sets a maximum length of the roof truss members. In some embodiments, the limitations of the manufacturing machines are used to set the required values. For example, the thickness of the material is a limitation on the roof truss members.

In decision 406, the conflict identification program 108 determines if the roof truss member's have any internal conflicts (e.g. if the actual values of the member properties are within the range of the required values). The measured actual values are compared to the required values. This comparison assists in confirming that the roof truss members are of the proper dimensions and have the features in the proper locations so that when the roof truss is assembled the members line up, the features of the members are in the proper location, and the roof truss is assembled correctly. If the conflict identification program 108 determines that an actual value of any properties of the roof truss member are outside the predetermined tolerance range of the property, the conflict identification program 108 creates the sick list and adds the identified member to the sick list.

In step 408, the conflict identification program 108 creates the sick list of the roof truss members which have issues. This list may be the identification of the members within the model as highlighted or identified from the other members. In some embodiments, the sick list is a list showing the actual values, the required values, and the differences between these two values (delta) and highlight the member data to alert a user.

In step 410, the conflict identification program 108 modifies the conflicting roof truss members. Through either an automated process or the selection of a user, the conflict identification program 108 is able to modify the conflicting roof truss members to fall within the tolerance range set for each property value which is conflicting. In some embodiments, this may require performing additional modifications to the roof truss member if the modification results in other features of the roof truss member becoming problematic and conflicting with the required values. For example, if a roof truss member is shortened and thus moving the position of an aperture, the aperture position may be adjusted to accommodate the shortening of the roof truss member.

In step 412, the conflict identification program 108 analyzes the roof truss members relative to the assembled roof truss. The conflict identification program 108 analyzes the roof truss members interaction with one another. This may include members are overlapping, incorrect placement of fastening positions, incorrect member direction or orientation at connections, incorrect gaps or spacing between roof trusses uneven height or width, are a few examples of potential internal conflicts. For example, the conflict identification program 108 may analyze the actual values of the orientation, position, length, width, and overlapping area of the top chord 902, the bottom chord 908, the end members 904, the center member 910, and the set of web members 912, 918, 914, 920, and 916 relative to one another to determine if there is any problematic overlapping or conflicts between the members. The set of web members 912, 918, 914, 920, and 916 orientation, overlap with one another and the top and bottom chords and the like are all analysed to determine the actual values for the members interactions. The location of the dimples relative on each track, and the other actual measurements of the interaction of the members. The bottom chords 908 are analyzed based on their actual overlap, their actual position, and their actual orientation relative to one another and the other members which interact with them.

In decision 414, the conflict identification program 108 determines if any of the members have external conflicts. The conflicts are based on the interaction between members of the roof truss. Based on the known requirements for the ideal interaction and a calculated value for the actual interaction between the members the conflict identification program 108 is able to determine if a conflict exists. If a conflict does exist the conflict identification program 108 creates a sick list of the external conflicts. If a conflict does not exist, the conflict identification program 108 completes the analysis.

In Step 416, the conflict identification program 108 analyzes the roof truss assemblies relative to the other roof truss assemblies and roof structure elements which the roof truss interacts with. This can be, that the assembly is of improper measurements, material, features, insufficient gap between two roof trusses or the like which would make the member have an internal conflict and not be possible to be created. If the member has negative or unrealistic values. The program analyzes vertical interface between each of the roof trusses for various features. Such as the required overlapping of each cold formed steel truss in horizontal and vertical plane is determined as per the location of junctions of truss and truss and gap required for proper connections of the assembly members. Actual overlapping of roof trusses and location of junctions of each roof truss assembly is determined from the actual position (coordinates) within the model.

In some embodiments, the program 108 analyzes for the interface of each roof truss assembly to determined the relationship between the trusses based on the global coordinates or position. The trusses should have sufficient gap (tolerance) in the horizontal direction while connecting with the trusses for proper connection. Actual gap (tolerance) between two overlapping trusses is determined based on the coordinates of the truss members.

In some embodiments, the program 108 analyzes for the interface of each roof truss assembly to determined the relationship between the trusses based on the global coordinates or position. The trusses should have sufficient gap (tolerance) in the vertical direction while connecting with the trusses for proper connection. Actual gap (tolerance) between two overlapping trusses is determined based on the coordinates of the truss members.

Placing of the trusses over the truss below it and connecting interface between the two trusses in horizontal plane is determined from the coordinates of the interacting members of the trusses. Both trusses should not overlap, and should not have a gap outside of the required value.

For proper connections, connecting trusses should have sufficient bearing area. Bearing area means when a truss is positioned above another truss, the area of interface between them is called the bearing area. For connection using screws it should have sufficient edge distances. Thus, the required bearing area is calculated from the number of screws required for the connection. Actual bearing area is obtained from locations of screws and their numbers used for connections by coordinates of the truss members within the model.

In decision 418, the conflict identification program 108 determines if any of the trusses have conflicts with other trusses. The conflicts are based on the interaction between the truss members of the interacting trusses. Based on the known requirements for the ideal interaction and a calculated value for the actual interaction between the members the conflict identification program 108 is able to determine if a conflict exists. The required minimum tolerance of each truss is determined as per the standard construction tolerances. The actual tolerance of each cold formed steel roof truss is determined from the model. If the required minimum tolerance and actual tolerance are same, then there is no conflict and if the required tolerance and actual tolerance are not same, then there is conflict. If a conflict does exist the conflict identification program 108 creates a sick list of the external conflicts. If a conflict does not exist, the conflict identification program 108 completes the analysis.

FIGS. 5, 6, and 7 depict various architectural illustration of a structure, in accordance with one embodiment of the present invention. The conflict identification program 108 may be provided these types of illustrations and analyses them to determine which features of the structure are the roof trusses. This determination is based on the position of the elements, the identified shape of the elements, the members (and orientation of the members) of the elements, and the like which would distinguish the roof trusses from the other elements of the building. In FIG. 5, the roof 502 is clearly shown on the top of the building. In FIG. 6, the roof 602 is clearing shown along with the overhang over the front and rear of the building. In FIG. 7 a dotted line 702 showing the outside edge of the roof is shown. This includes both internal and external roof trusses. Through the analysis of the building design, the conflict identification program 108 is able to establish a set of limits and requirements which the roof trusses and the roof truss members must adhere to. These illustrations depicted the floor plans to show walls, doors, stairs, windows, rooms, and other architectural features of each floor of the building. Based on the conflict identification program's 108 review of these drawings, the program is able to detect the overall dimensions of the roof trusses to assist in setting forth the required values and properties to which the roof truss members are analyzed.

FIG. 8 depicts a model 800 of a frame of a structure, in accordance with one embodiment of the present invention. This model provides all of the framing members including the walls, floors, and roofs.

In the depicted embodiment, the model depicts the structural framing members, with all the connection points for the frame members determined. This model would be analyzed for each structural wall member to determine any conflicts. If a conflict is found, that member may be highlighted or identified in a different color to allow easy visual identifies for the user to locate the conflict member.

This is an analysis relative to the horizontal interface between trusses, the vertical upper handshake and the vertical lower handshake. The horizontal interface is shown in FIGS. 9 and 10, where a secondary truss 902 is secured to a main truss 904. The measurements have a tolerance of a maximum and minimum which the distances can be between to not be conflicting.
